IMPROVEMENT IN REFRIGERATING PROVISION-CARS.

Specification forming part of Letters Patent No. 123,078, dated January30, 1872; antedated January 15, 1872.

I, JOHN J. BATE, of the city of Brooklyn, in the State of New York, haveinvented certain Improvements in Refrigerating Provision- Oars, of whichthe following is a speciiication:

This invention has reference to an arrangement of means for drawing theair from the provision-chamber near its top and delivering it cooled andpurified at the bottom of the chamber. I

The accompanying drawing shows a car, of which a indicates the door, bthe roof, and c the ends. In Figure 1 the roof is removed to show theinterior of the car, and Fig. 2 is a view, by vertical section, on thedotted line of Fig. l. d indicates the provision-chamber; e, theice-chamber; f, the messengers room. In the messengers room or in theice-chamberis placed a fan-blower, g, which is operated by a band orcord, h, passing around a pulley on its shaft and around a pulley, i,which is operated by a band from and around the axle of the car. To theinlet of the blower is attached a tube, j, and to the outlet anothertube, k. The tubel j is coiled in the ice-chamber, as is shown by Fig.2. The tube 7c lies upon the floor of the car, and can be perforated bythe escape of the air, or the only escapeopening may be at the end ofthe tube. A hinged door, l, is at the bottom of the partition betweenthe ice-chamber and the provision-chamber to control the space m. Whenthe blower is not in action the door l will be left open so that therewill be a circulation of air from the provision-chamber through thespaces m and n.

When the blower is in operation and the door l closed the airfrom theprovision-chamber will be drawn through the space n and through theupper portion of the ice-chamber to the mouth ofthe tube j, passingthrough the blower and through the tube k, and be delivered at thebottom of the provision-chamber. This arrangement of means is intendedto use the air of the chamber over and over again, and thus keep the aircool and pure'.

For store-rooms or warehouses or provisionchambers in buildings suchmotive power as is at hand may be used to operate the blower. In somecases I prefer touse watch or clock movements, and to actuate them byIndia-rub` ber springs instead of metallic springs or weights.

In the bottom of the ice-chamber there will be the usual drip or siphonfor drawing 0H the water therefrom.

I am aware that it is not new to so construct provision-cars as to havea forced circulation of air, the same being set forth in the patents toD E. Somes, granted in 1867 and 1868, and in a patent granted to W.Bray, 1867 5 and I therefore limit my claim to such an arrangement ofmeans for such circulation as is difiere ent from either of theinventions here referred to.

Claim.

The arrangement of the coiled tube j in the ice-chamber in relatlon tothe space n, fanblower g, and tube k for drawing the air from the upperpart of the provision-chamber and delivering it near the bottom thereof,as herein recited.

This speciiication signed this 12th day of April, 1871.
